The Green Bank Northern Hemisphere survey (gb1) published its results in papers published from 1968 to 1982 with a total of 31 new pulsars discovered. It detected a grand total of 19 pulsars. The fastest pulsar discovered was J0700+6418 with a period of 195.67095 milliseconds and the slowest pulsar was J0528+2200 with a period of 3.74554 seconds.
The smallest pulsar dispersion measure was J0814+7429 with a DM of 5.75066 pc/cc and the largest pulsar dispersion measure was J2325+6316 with a DM of 197.37 pc/cc. This survey detected a pulsar in 1968, the first year of pulsar astronomy.
